While many members of the rhizosphere microbiome are beneficial to plant growth, also plant pathogenic microorganisms colonize the rhizosphere striving to break through the protective microbial shield and to overcome the innate plant defense mechanisms in order to cause disease. Microbial communities inhabiting the plants’ surface (rhizosphere or rhizoplane; epiphytic) or inner tissues (endosphere; endophytic) assist their hosts’ development by improving their resilience to inorganic and organic pollutants and by changing their bioavailability in soil. It also helps boost crop vigour, enhance immunity against biotic and abiotic stress and thus boost overall crop productivity. For instance, integrative approaches in the combined use of different relevant microbial groups (e.g., bacteria and fungi) to harness phytoremediation are still underexplored, as are their interactions with the host plants and their microbiomes. Drought stress not only effect the population and activities of microorganisms inhabiting the rhizosphere but also various physiological and biochemical process in plants that is, photosynthesis, respiration, translocation, uptake of ions, carbohydrates, and nutrient metabolism.
